Part I: An Introduction to Plant Breeding and Seed Saving 1 Amateur Vegetable Breeding 3 Why every gardener should be a plant breeder. Stories of three amateurs and what they've done. 2 How Much Space Do You Need? How Much Time? 17 Vegetable breeding can be done on any scale. You can do an elaborate tomato-breeding project in a few half-gallon pots of soil, or a pea-breeding project in a few feet of row. Some projects require only a year or two to produce material that is an improvement over anything available commercially. 3 Roles and Goals for Amateurs; Wish Lists and Wild Ideas 23 Breeding for flavor. Breeding for size, shape, color, earliness, cold or heat resistance, disease resistance, regional adaptation, yield. Breeding as an expression of individuality, for your tastes and needs. Breeding varieties that do well under organic gardening or farming methods. Breeding new and unusual crops. Discovering popbeans and tiny fast-cooking chickpeas (garbanzos). Thinking small, thinking big, daring to dream. 4 Finding Germplasm 42 Obtaining germplasm and information about it. How to work with seed companies, seed saving organizations, and plant science professionals. How to gain access to and use the collections of the USDA-ARS National Plant Germplasm System. 5 Evaluating Germplasm and Experimental Material; Variety Trials and Gardening Research 54 How to design, conduct, and evaluate garden trials. How to combine trials with production of food and beauty. How to get good information with the least amount of land and labor. 6 Genetics and Plant Parenthood 77 7 Sex and the Single Gene; Mendel's Genes 85 8 Modern Genes 93 9 The Genetic Basis of Seed Saving 111 Inbreeding and the genetic nature of inbreeding crop varieties. Saving seed from inbreeders. Heirlooms. Outbreeding and the genetic nature of outbreeding crop varieties. Inbreeding depression. Outcrossing and self-incompatibility. Saving seed of outbreeders. Inbreeder or outbreeder - how you can tell? Saving seed from hybrids. Making and breaking hybrids. 10 Plant Breeding Stories 126 Popbeans and purple peas. Perennial vegetable buckwheat and perennial lettuce-salsify. Power selection, power inbreeding, crosses, backcrosses, and recurrent backcrossing. 'Rainbow Inca' sweet corn. Tomatoes, squash, and melons. 11 Bigger, Brighter, and More Beautiful 148 Creating polyploids. Chromosome doubling using colchicine. Breeding with established polyploids. 12 Fun with Wide Crosses 152 Crosses between distant relatives within a species. Crosses between different species. Creating entirely new crop species. 13 Happy Accidents 156 Taking advantage of new mutations, sports, bud sports, and accidental crosses. More cold-hardy fava beans, bigger tomatoes, and giant top-setting onions. 14 Domesticating Wild Plants 163 15 Expanding Horizons 172 Table I 801 Interesting Plants 175 Vegetables of the world and their wild relatives; edible plants that have the potential for being developed into vegetables; fruits, nuts, and grains. Scientific names, common names, families, and lifestyles. Basic breeding systems, chromosome numbers, flowering patterns, flower types and modifications, average cross-pollination frequency, major pollen vectors, and incompatibility system information. Recommended isolation distances, seed yields, location in the USDA-ARS National Plant Germplasm System, and references.
Part II: Seed Saving Practice 16 An Introduction to Seed Saving 209 Why save seeds? Seed-saving overview. Saving seed from hybrids. Roles and purposes. 17 Growing Seed 213 Preparation and planning, planting, tending. 18 Isolation 218 Traditional seed saving and isolation distances. Isolation distances for organic farmers and gardeners. Isolation basics. Factors that affect the need for isolation. Isolation distances, absolute and practical. The Basic Rule for Everyday Seed Saving. Isolation tricks and methods. 19 How Many Plants? 232 Inbreeders and outbreeders. Practical compromises. 20 Selection 237 Selection basics. Selection complexities, subtleties, and surprises. Selection for the purpose of germplasm preservation. Evaluating a selection program. Does selection always work? 21 Harvesting, Processing, and Storing Seed 243 Harvesting, threshing and cleaning. Dry and wet processing. Drying seed. Protecting seed from insects and rodents. Storing seed.
Part III: Developing Crops for a Sustainable Future 22 Genetic Engineering and Genetically Modified Foods 261 Carol Deppe meets the FlavrSavr tomato. Standard plant breeding versus genetic engineering. Everything in this book is illegal with genetically engineered varieties. Genetic engineering and sustainable agriculture. 23 Conversations with a Squash 272 Why not just select? Choosing the right cross. The agroecological virtues of a squash. The grand plan. Choosing the cytoplasm. The reality. The squash speaks. Carol falls in love. Disaster and opportunity. Sandwich-slice. To market, to market, to sell a new squash.
